Iam doing my first desert trip in late July (29th launch) and I have never had to worry all that much about "cooler management ". 8 days plus travel to put in I guess? Deso with two big coolers and one medium or at least I have them to use? We usually (or have anyway) frozen meals in vacuum bags as well as frozen some water and kinda did the "don't open cooler" but we live where it's cool and so it wasn't hardcore. I've had ice after 5 days but never tried to hard. I'd like to see just how far you guys can take it . Lol! So you desert gurus school us alpine guys on the art a d science of "cooler management "
